Description
Perturbative expressions for many QCD observables measured at colliders are plagued by large logarithmic corrections which arise after cancellation of real and virtual contributions. These large logarithmic corrections, which arise either at small $Q_T$ or at partonic threshold can be organized and brought under control through all order resummation. Joint resummation formalism allows simultaneous resummation of threshold and recoil effects.
We consider the effect of the leading soft-collinear terms of the form $α_s^i\Sigma_{j}^{2j−1}d_{ij}\frac{ln^j N}{N}$ and estimate the impact of leading soft-collinear effects on joint resummed calculations for prompt photon production.
